Smart grids have been proposed as a way to increase grid robustness and reduce consumption peaks and at the same time decrease electricity costs for the end users. This thesis aims to develop generic models for smart grids focusing on smart houses which are used to test if it is possible to reduce consumption peaks, decrease electricity cost and at the same time increase grid stability. Models hav
Electrical machines in electrical vehicles are sometimes put under a lot of stress when for example climbing an uphill road. In order for the machine to cope with the heat generation that comes of running extended periods of time near or at peak power one needs a highly developed cooling system. At the division of Industrial Electrical Engineering and Automation (IEA), located at Lunds Tekniska Hö
Abstract Future climate change scenarios project a water temperature increase of 2 to 5 ˚C for the upcoming 100 years. Simultaneously, north temperate zones will face precipitation changes that will ultimately enhance humic content and water colour in freshwater systems. I hypothesised that increased temperature and water colour would benefit the grazing activity of mixotrophs, and the dominance
Som ett steg i utvecklingen av nästa generations hjullastare görs studier av olika delsystem för att se var energiförbrukningen ligger. Denna masteruppsats har som mål att ta reda på energiförbrukningen för fyra länkage med olika konstruktion. Den kommer även att undersöka hur energiförbrukningen förändras när en elektro-hydraulisk kompensering introduceras för att hålla lasten parallell samt vad As a stage in the development of the next generation of wheel loaders, all systems are evaluated in order to minimize the energy consumption. This master thesis aims to investigate the energy consumption for four linkages with different design. It will also investigate how the energy consumption changes when an electro-hydraulic compensation is added in order to keep the load parallel and what the
To be able to change gears in a transmission it is necessary to remove the torque when disengaging and engaging gears in order not to damage the teeth of the cogs. If the driving torque from the engine to the wheels is interrupted for a longer period of time it can be perceived as very uncomfortable for both the driver and passengers in the vehicle. A gear change can be divided into three main sta
Quantum entanglement between electrons in nanostructures is a key concept of quantum information still waiting to be experimentally demonstrated. In this master's thesis we present and analyze the full counting statistics of the charge transfer of a sextuple quantum dot system which works as both entangler and detector of spatially separated electrons. Under certain resonance conditions the sy

With the diminishing reserves of oil and the growing public concern for environmental issues, the end of gasoline powered vehicles is getting closer each year. To prevent this from causing the personal and comfortable way of transportation mankind has gotten used to, to die with them, an alternative without the downsides of the gasoline engine must be developed. The environmentally friendly electr
In 1996 the European Union adopted the Seveso II Directive. The Directive stated actions to be taken in the process industry in order to prevent and limit the impact of serious chemical accidents. In the Directive it is clearly stated that domino effects shall be considered, but the level of detail required is not specified. Due to that fact and the high degree of complexity linked to domino e
Reduction of the cleaning time is an important issue for companies using large tanks. A common solution is a stationary pipe going into the tank with a cleaning nozzle mounted on the end. Today the spray pattern of most cleaning systems is fixed. It would be beneficial to adjust the cleaning cycles so that the most soiled places of the tank get extra attention without increasing the total cleaning
Climate change is exponentially becoming one of the most pressing issues of our time. While it is an issue that plaques the international community it is an issue that needs to be addressed on all levels. Local government has been highlighted as the level closest to the people and is uniquely positioned to instigate a range of activities that directly address climate change and sustainability. Thi
Happiness is a relatively new discipline within economics. Traditionally, economists have not paid too much attention to it since they considered that both indicators and theoretical assumptions in which this discipline was based were not neither reliable nor useful for policy recommendations. However, especially in the last decade, there has been extensive research which, if not proved, at least
Kommunernas naturvård bedrivs av många olika anledningar. Politikerna och tjänstemännen prioriterar olika områden och naturvårdens status i kommunerna är inte alltid vad den borde vara. Detta bidrar till att naturvårdsfrågorna inte får de utrymme som de behöver för att säkerställa ett gott artskydd. Att naturvården sker i kommunal regi är den vanligaste formen av naturvård, då naturområdena inte In this study I have examined which conditions that play a role in the conservation of natural environment. The results in this paper have been analysed from interviews that I have conducted with conservation officers working with conservation efforts in local municipality's in southwest Skåne, Sweden. In the process, I have come to the conclusion that the nature conservation the conservation
The aim of this thesis is to study the anthropology of contemporary Swedish ecotheology and theology of creation, Bo Brander, Per Larsson and Wilfrid Stinissen, in comparison with the ecofeminist theology of Sallie McFague. The Swedish theologians in this study describe man as steward, microcosm, priest, co-sufferer and the image of God. McFague use the term partner when describing man, a term w
This research aims to explore how consumption impacts on the construction of affiliation boundaries within heterogeneous consumption-oriented subcultures. In order to accomplish this purpose, we have studied the growing phenomenon of barefoot running in relation to the consumption of minimalist footwear as a symbolic product. By doing so, we have explored how consumption vertebrates the subculture
